FLifetimePropertyThis class is used to track a property that is marked to be replicated for the lifetime of the actor channel. This doesn't mean the property will necessarily always be replicated, it just means: "check this property for replication for the life of the actor, and I don't want to think about it anymore" A secondary condition can also be used to skip replication based on the condition results
